The history of the Mandir-Masjid dispute during the post-Independence period is but a record of aggression by Hindu communal forces, and a series of compromises and reconciliation bids by the Central government led by the Indian National Congress, particularly under Prime Minister Rajiv Gandhi and Prime Minister P.V. Narasimha Rao.
The demolition was a criminal act according to the laws of the country, as the mosque was a 400-year-old historical monument that the state was committed to protect.
The leader who initiated this disastrous policy was Rajiv Gandhi. He ordered the opening of the locks of the Masjid, thereby permitting Hindus to perform puja inside. He did this in order to steal the thunder from the Hindu communal forces. His successor-Prime Minister pursued the policy of compromise much more vigorously, and ‘officially arranged' the shilanyas of the temple. The Congress thus became an appendage of communal forces; that is what emboldened a mob to demolish the Masjid, thus inflicting a major blow on democracy and secularism.
The failure of the Indian state was a most decisive factor behind the act of demolition. As is evident from the account given later by Narasimha Rao, it is clear that the state failed to discharge its duty of protecting the monument. It failed to prevent Mr. Advani's Rath Yatra, which led to the loss of several lives: everybody knew it would have disastrous consequences. Even after the demolition, the construction of a temporary temple was not stopped. At least now the state can rectify its mistakes by charting out a bold and innovative step in line with the principles of secularism.
